Dynamic array....probab le memory allocation problem..need advise!

[Baka otaku]

The program I need to write must accept code no, name and total bill amount for "n" number of customers and then print all the things along with the grand total. I worked out the program and while building it shows no errors. while debugging, it takes the first set of values but after that it says - The instruction at "0x00402161 " referenced memory at "0xcccccccc ". The memory could not be "written". Is there something wrong with the program or memory...please help.

The code is :

#include<iostream>
using namespace std;
 
class customer
{ private:
int ncust;
int *codeno;
char **name;
int *tbill;
 
public: 
void cust_accept(void);
void cust_print(void);
};
 
void customer::cust_accept(void)
{ cout << "Enter the total number of customers " << endl;
cin >> ncust;
codeno=(int*)new int[ncust]; 
name=(char**)new char*[ncust];
for (int i=0; i<ncust; i++)
{ name[i]=(char*)new char[20];
}
for (int j=0; j<ncust; j++)
{ cout << "Enter the customer code no " << endl;
cin >> codeno[j];
cout << "Enter customer name " << endl;
cin >> name[j]; // insert name of customer
cout << "Enter the total bill amount " << endl;
cin >> tbill[j];
}
}
 
void customer::cust_print(void)
{ for(int i=0;  i<ncust; i++)
{ cout << "Customer" << endl; 
cout << "Code no   Name   Total Bill amount " << endl;
cout << codeno[i] ;
cout << name[i] ;
cout << tbill[i];
}
int gtotal;
for (int j=0; j<ncust; j++)
{gtotal+=tbill[j];
cout << endl;
cout << "Grand total" << gtotal;
}
}
 
 
int main ()
{ customer srec;
srec.cust_accept();
srec.cust_print();
return 0;
}
 
 

[horace1]

the memory you allocate for name is the number of customers

name=(char**)new char*[ncust];
 

so if ncust is 3 each name is a maximum of 2 characters long
perhaps it should be

name=(char**)new char*[20];
 

and the name can be up to 20 characters long.

would it not be better for class customer to hold data on one customer and then have a vector of customers?

    vector<customer> v;
